These chicken fajita sliders are everything I love about a quick, flavor-packed dinner! They are made with juicy seasoned chicken, sautéed peppers and onions, melty cheese, and soft Hawaiian rolls baked until golden and buttery. They’re easy to make, but feel like something a little special when they come out of the oven. I use my homemade chicken seasoning to really build that bold fajita flavor, and if you love those flavors, my air fryer chicken fajitas are another easy weeknight favorite. And if sliders are your thing, I’ve got a whole collection of my best slider recipes you’ll want to check out next.
Ingredients & Substitutions
- Chicken breasts: Thinly sliced for quick cooking and maximum flavor absorption. Chicken thighs can also be used for a juicier option.
- Best chicken seasoning: My homemade seasoning builds the base fajita flavor. You can substitute a store-bought fajita or taco seasoning if needed.
- Onion & bell peppers: Classic fajita vegetables that add sweetness and color. Use any color peppers you like or what you have on hand.
- Tomato paste: Adds richness and depth to the filling. You can substitute with a spoonful of salsa in a pinch.
- Chili powder & red pepper flakes: Add warmth and heat. Adjust or reduce depending on spice preference.
- Hawaiian rolls: Soft and slightly sweet rolls that hold everything together. Any soft slider buns will work.
- Pepper Jack cheese: Adds creaminess and a little heat. You can swap with Monterey Jack or cheddar.
- Mozzarella cheese: Helps create that melty, gooey cheese layer. Provolone also works well.
- Garlic Butter Topping: A simple garlic butter made with melted butter, parsley, and garlic powder is brushed over the rolls before baking for a golden, flavorful crust.
FAQs
Can I make chicken fajita sliders ahead of time?
Yes. You can prepare the chicken fajita filling up to 2 days ahead and store it in the refrigerator. Assemble and bake the sliders when ready to serve.
Can I use rotisserie chicken instead?
Absolutely. Skip the chicken cooking step and toss shredded rotisserie chicken with the seasonings, tomato paste, and cooked peppers and onions until warmed through.
What cheese works best for fajita sliders?
Pepper Jack adds a little heat and melts beautifully, while mozzarella gives the sliders that extra gooey texture. Monterey Jack, cheddar, or provolone also work well.
Can I make these sliders less spicy?
Yes. Reduce or leave out the red pepper flakes and use a mild cheese if you want a milder version.
How do I keep the sliders from getting soggy?
Let the fajita filling cool slightly before assembling, and avoid adding excess liquid to the pan. Baking uncovered at the end also helps keep the tops crisp and golden.
Can I make chicken fajita sliders in the air fryer?
If your air fryer is large enough, you can bake smaller batches at 325 to 350°F until the cheese is melted and the tops are golden. Smaller slider buns tend to work best for this method.
What to Serve with Chicken Fajita Sliders
These chicken fajita sliders pair well with all kinds of easy sides, whether you’re serving them for dinner, game day, or a party spread. Some favorites to serve alongside them include:
- Air fryer French fries
- Chips and skillet queso dip or roasted salsa
- Mexican rice or cilantro lime rice
- Pasta salad or coleslaw
- Guacamole and homemade tortilla chips
How to Store Chicken Fajita Sliders
Store leftover sliders in an airtight container in the refrigerator for up to 3 days. For the best texture, reheat them in the oven or air fryer at 350°F until warmed through, and the tops are crisp again. The microwave works for a quick reheating option, but the rolls will be softer.
Chicken Fajita Sliders
Ingredients
Fajita Chicken & Vegetables
- 1 ½ pounds boneless skinless chicken breasts, thinly sliced
- 2 tablespoons chicken seasoning
- 2 tablespoons olive oil divided
- 1 medium yellow onion, thinly sliced
- 2 medium bell peppers, mixed colors, thinly sliced
- 1 pinch Kosher salt
- 2 tablespoons tomato paste
- 1 teaspoon chili powder, or more to taste
- ½ teaspoon red pepper flakes, adjust for heat
Sliders
- 1 package (12-count) Hawaiian rolls, (such as King’s Hawaiian)
- 6 slices Pepper Jack cheese
- 1 cup (113 g) mozzarella cheese, shredded
Garlic Butter Topping
- ¼ cup (½ stick / 57 g) unsalted butter, melted
- 2 tablespoons fresh parsley chopped
- 1 teaspoon garlic powder
Instructions
Fajita Chicken & Veggies
- In a large bowl, toss the sliced chicken with 1 tablespoon olive oil and the chicken seasoning until evenly coated. Cover and marinate for at least 30 minutes (or overnight for a deeper flavor).
- When ready, heat the remaining 1 tablespoon olive oil in a large skillet over medium-high heat. Add the sliced onions and bell peppers with a pinch of salt. Cook for 5 to 7 minutes, until softened and lightly caramelized. Remove from the pan and set aside.
- In the same skillet, cook the chicken (in batches if needed) until fully cooked through to an internal temperature of 165°F and lightly charred, about 6 to 8 minutes.
- Stir in the tomato paste, chili powder, and red pepper flakes. Cook for 2 to 3 minutes, until the tomato paste darkens and coats the chicken.
- Return the cooked peppers and onions to the skillet. Toss everything together until well combined. Remove from heat.
Assemble the Sliders
- Preheat oven to 375°F (190°C).
- Without separating the rolls, slice the entire package of Hawaiian rolls in half horizontally. Place the bottom half in a 9×13-inch baking dish.
- Layer with Pepper Jack cheese, then sprinkle with ½ cup of the mozzarella cheese.
- Spoon the chicken fajita mixture evenly over the cheese. Top with remaining mozzarella, then place the top half of the rolls on.
Garlic Butter Topping
- Mix melted butter, parsley, and garlic powder. Brush generously over the tops of the rolls.
- Cover with foil and bake for 15 to 20 minutes, until cheese is melted.
- Remove foil and bake an additional 5 to 8 minutes, until tops are golden brown.
- Brush with any remaining butter if desired, then slice and serve warm.
